Talk about shocking! Flat Battery is jumpy, jittery and constantly on edge, he's the one who will light up (or set fire) to any occasion!
Flat Battery is a cylindrical battery with a banged-up body. He has red lightning bolts on his body, and has eyes going in different directions, with a crazy, toothy grin. He is coated with mold on the top of him.
- Flat Battery is similar to Zapper, a Trashie from Series 2 of the Trash Pack.
- In the webseries, he is given the name Surge. In the webseries, his design has added stress wrinkles around his eyes. He also has a stutter when he speaks on some words.
- He is one of two battery-based Grosseries from Series 2, the other being Leaky Car Battery.
- His static art gives him a missing tooth, which his figure lacks. He is also depicted with yellowed teeth in his figure, instead of white teeth in his static art. He does appear to have a gap printed for a missing tooth in his catalog art, however.
